Hello Old Friend

Citizen Scientist, amateur astronomer, and ham radio satellite sleuth Scott Tilley, VE7TIL used his camera to capture an old friend streaking across the heavens, the AO-40 satellite.

Testing the RASA 8" again this night and came across @amsatdl's AO-40. It's very dim but detectable on the system. The spacecraft's light curve is variable. These are 5s exposures. pic.twitter.com/LzUUNezoYP
